The organic composition of carbonaceous meteorites: the evolutionary story ahead of biochemistry.

Abstract in brief

• Organic compounds in meteorites, including complex macromolecules and simple molecules like amino acids, offer a glimpse into extraterrestrial chemistry that predates life on Earth.
• Many of these meteoritic molecules are identical to Earth's biological molecules and suggest a long history of chemical evolution in space, with isotopic data indicating they formed in presolar environments.
• It remains uncertain whether this cosmic chemical evolution directly influenced the origin of life on Earth, but the prevalence of biologically relevant molecules in meteorites hints that they may have contributed to terrestrial molecular evolution.]
